ManDrake

ManDrake is a native, open source man page editor for OS X. It has syntax highlighting, live mandoc syntax validation and a live-updating rendered preview of the man page during editing.

Long story short, I was sick of writing man pages in an endless cycle of edit-view, edit-view so I decided to do something about it and made this editor. It's a bit rough around the edges, but it works really well for me. Maybe it will also be of some use to you.
